| 摘 要： | 提出了消除钢-Al-20Sn复合板复合界面脆化的非均匀扩散思想,并采用Al-20Sn半固态浆料与钢板进行铸轧复合,实现了非均匀扩散,改变了复合界面结构,消除了复合板复合界面的脆化。研究结果表明,在500℃钢板预热温度、10mm/s铸轧速度条件下,当半固态浆料固相率为34.3%时,复合界面由比例恰当的铁铝化合物和铁铝固溶体交替构成,脆化得以消除,相应的最大界面剪切强度为69.9MPa。 |

| Abstract: | Nonhomogeneous diffusion thought to eliminate the embrittlement of steel-Al-20Sn interface was presented and realized by conducting steel-mushy Al-20Sn rolling casting bonding. The interfacial structure changed and the interfacial embrittlement was eliminated. The results showed that under the condition of 500℃ steel plate preheat temperature and 10mm/s rolling casting speed, when solid fraction was 34.3%, the interface was made up with the right Fe-Al compound and solid solution alternatively, and because of the elimination of interfacial embrittlement, the maximum interfacial shear strength was 69.9MPa. |
| Keywords: | rolling casting bonding solid fraction interfacial structure interfacial shear strengt |
